Patent DE-3723656-A1 (DE)
Title: Shaped drainage block consisting of concrete
Inventor: ARLT GERHARD
IPC: F16L21/03
Filed: 1987-07-17
Abstract: A shaped drainage block (3) consisting of concrete or of another material which sets firmly after shaping has an integrated clearance (2), in whose wall (1) there is concreted or cast a sealing insert (4) which consists of an elastomeric material and belongs to a plug-in sleeve (5) provided with a radial widening portion (12). In comparison with the known sealing inserts of plug-in sleeves of this type, the cross-section of the sealing insert (4) has been reduced such that individual parts or all those parts of the sealing insert (4) which cover the inner wall of known plug-in sleeves as a lining are partially or wholly emitted. As a result of these reductions and simplifications in the cross-sectional shape of the sealing insert (4), considerable savings in costs are achieved for the production of the plug-in sleeves (5) without their functional reliability being thereby impaired. The shaped drainage blocks (3) according to the invention, which are equipped with the novel cost-saving plug-in sleeve (5), are, in practice, preferably used as street inlets, street gulleys, cleaning pipes, concrete-pipe branches and transition pipes, said plug-in sleeves (5) also being suitable for the sealed connection, which is secured with respect to shearing loads, of pipes with pronounced tolerance requirements, for example of stoneware pipes. <IMAGE>

Title: Device for agitating a particulate material, in particular for mixing and/or spraying the material
Inventor: JAEGGI MAX
IPC: B01F29/60
Filed: 1987-08-05
Abstract: The device has a frame (3) and a vessel (11). This vessel is mounted in the frame (3) to be able to rotate about the horizontal vessel axis (13), can be driven by a drive apparatus and is provided with a wall having at least one conical shell (29, 329). In the, or each, conical shell (29, 329) there is situated a conical interior wall (35, 335). The intermediate space present between this and the shell (29, 329) is subdivided by partitions (39, 339) into compartments (33b, 33d), which are connected together and to a space region (33a, 33c) surrounded by the at least one interior wall (35, 335) at the two edges (35a, 35d) of the, or each, interior wall (35, 335). When the vessel (11) is rotated, a particulate material situated therein is transported upwards in portions by the compartments (33b, 33d) and then falls down again. An intensive and gentle mixing process takes place in this case, without the risk of lubricants from bearings or other pollutants passing into the particulate material. <IMAGE>
Patent DE-3728029-A1 (DE)
Title: Apparatus and method of recording, representing and optimising the process quality at the working gap of an electrical discharge machining unit
Inventor: VOSS WOLFGANG
IPC: B23H7/16
Filed: 1987-08-22
Abstract: The invention describes an apparatus and a method which records the ignition delay and the voltage drop of the individual discharges of an electrical discharge machining unit and thus classifies each discharge with only two values. The spark process is classified by sorting a multiplicity of discharges thus classified into a two-dimensional data field. The two-dimensional data field is output as a false colour image on a monitor. The respective spark process can thereby be evaluated by the operator and is therefore easy to optimise.

Title: Refuse bin opener with foot operation
Inventor: DOERR WILHELM ING GRAD
IPC: B65F1/16
Filed: 1987-08-27
Abstract: The designation is: Refuse bin opener with foot operation. My Patent No. 3313309.3.  My Patent Application No. 3700264. These patents use the lid handles to open the lid and are also dependent on the type of bin handles. Both bin and lid handles have complicated the designs and increased production costs because of their many shapes. Another approach has therefore been sought and found. The results are:     1) The lid handles no longer play any part.   2) The bin handles no longer play any major part.   3) The lid is raised on the lid arm.   4) The angle of opening is larger (60@).   5) The new opener is lighter (2300 grams).   6) It is easier to produce.   7) It is cheaper to produce.   8) Also improved ease of handling for handicapped people.   The apparatus is placed unchanged on the bin onto a running wheel, and the lid arm is inserted by lifting the lid by hand, the lid being let down into the U-shaped stirrup (14). When the foot pedal is operated the lid is raised on the lid arm via a lever arm and a lifting rod with an articulated U-shaped stirrup (14). When the foot is removed, the lid closes as a result of its own weight. <IMAGE>

Title: Method for applying contact decks to a substrate
Inventor: GLAESER HANS JOACHIM DR
IPC: H05K3/24
Filed: 1987-12-01
Abstract: In a method for applying contact decks (6) to a substrate (1) consisting, in particular, of glass or the like which has an electroconductive coating (2), the coating (2) is removed chemically or mechanically from the substrate (1) at those points where a contact deck (6) is planned, and there is applied to the substrate (1), at this layer-free point, by flame-spraying or the like, a conductive solderable alloy, especially a copper alloy. This then has a conductive suspension applied to it which may also overlap zones of the electroconductive coating (2). Current leads can then be soldered on in a conventional manner. Large-area coated substrates can therefore be cut to size prior to the contact decks being applied. Advantageously, the contact decks are applied in edge zones of the substrate (1). <IMAGE>

Title: Electrical power supply device having various electric tools which can be connected thereto
Inventor: FETZER GERHARD DIPL ING
IPC: H02P4/00
Filed: 1987-08-07
Abstract: An electrical power supply device is proposed having various electric tools (10) which can be connected thereto via a connecting cable (16) having a connecting plug (22). This electrical power supply device (13) contains an electronic controller (14) for controlling the electric tools (10) as a function of at least one parameter. A coding appliance, which is constructed as a digital memory (30), is tool-specific and can be picked off by the electronic controller (14) via the connection to the electric tool (10), is used for accommodating identification data such as apparatus type, apparatus number, date of sale, owner or the like and/or for accommodating defect signals (error signals) occurring during operation. In consequence, a large amount of necessary and useful data can be called up in a simple manner, for example in the event of a repair, which data not only specify the respective electric tool but may also contain information on the type of defect. <IMAGE>

Patent DE-3841851-A1 (DE)
Inventor: PEREVOZKIN JURIJ LEIBOVIC
IPC: B22C9/04
Filed: 1988-12-13
Abstract: The method consists in short-time treatment of a block of patterns of wax-like pattern material covered by a refractory shell by blowing onto the block, steam having a temperature of 110-140 DEG C during 5 to 90 seconds. The surface layer of the pattern material melts very quickly and a gap is formed between the pattern and shell. After that this block is treated with hot air. By this all pattern material is heated, melted, and removed from the shell. The steam treatment for a short time permits the use of water soluble binding materials for making the shell, and the initial melting of the pattern surface layer avoids expansion of the unmelted core, exerting stress upon the refractory shell which would cause it to crack.
